The part when the files are being unpacked from the cd takes approximately 40 minutes. After the normal reboot, "Starting Windows 7" just hangs without change. This is a brand new PC that came without OS installed (our option). Installing the files from a USB stick went in a few minutes, but the thing hangs after the reboot anyway. This tells me that both the SSD (LiteOn) and the DVD rom is not working. Any help is appreciated.
